Pots with with round or D shafts require knobs with plain holes that if not push fit, have set screws to hold them in place. Most spline shaft pots have a slightly smaller diameter shaft than round or D shaft. Usually splines are 6mm while most round ones are 1/4" (6.35mm). So 1/4" setscrew knobs will end up slightly lopsided when tightened onto a 6mm spline shaft. Knobs fastened by a collet require a box spanner to fasten them.<ref>[https://www.muffwiggler.com/forum/viewtopic.php?t=54215&sid=0c1a5b9d1c9d353c1a8e025489dcf6ac knurled vs round shaft pots], Muff Wiggler forum, March 2012</ref><ref>Wikipedia: [https://en.wikipedia.org/wiki/Control_knob Control knob]</ref>
